THZ-100 THERMOSTAT

Welcome To Your THZ-100 Thermostat

Congratulations on your purchase of this THZ-100 Thermostat from
URC. Enjoy the full functionality of a stand-alone thermostat coupled
with the ability, when used with a Total Control system, to be controlled
from any user interface in the system. No more shivering under the
covers, dreading to dare the inevitable cold on the way to the shower;
grab the remote and make it nice and toasty, before removing the
blanket!

Some of the advanced, and unique features found on the THZ-100 are:

Optional Wired Sensor

Easily add an additional sensor to the thermostat by purchasing the
optional wired sensor. With the ability to temperature average between
the sensor and the main unit, or simply take the place of the main
unit’s on-board sensor, you can increase both efficiency and accuracy of
temperature readings.

Intelligent Comfort Recovery

Every good thermostat has the ability to set heating and cooling schedules,
but if you wake up at 7:30am, setting your heat to come on at 7:30am
means waking up to an uncomfortable home while your system reaches
your desired temperature. With Intelligent Comfort Recovery, the THZ-
100 monitors the current temperature of your home and determines the
amount of time it will take to reach your desired temperature at the
desired time. Then, it slowly and more efficiently heats or cools to the
new set point.

Security Code

Perfect for most commercial uses, and even for some homes where
people have the need to ensure that only authorized people should
have access to the THZ-100. Easily program your new thermostat
with a 4-digit security code to make sure that only people with the
code can access the thermostat.

Total Control Peripheral

Perhaps the best benefit is the THZ-100's complete integration into
a Total Control home system. When used with URC’s Total Control
system, the thermostat control can be accessed from any of the system’s
interfaces (dependent upon the system programmer). With the ability
to control all of the THZ-100s in the home, it is also easy to incorporate
heat/cool set points into various Automation Activities. Although the
possibilities are endless, imagine a Goodnight button that would turn
off your theater, turn off all the lights and bring the THZ-100 to the
chosen set point!

Installing Your THZ-100 Thermostat

Adding an optional wired sensor can be a benefit if the thermostat
location is not the optimal location for temperature measurement,
or if temperature averaging is desired.

• A wired sensor can be connected to the S+ and S- terminals
on the back of the unit

• This can be added to any of the wiring options detailed in the
next pages

For optimum performance, mount the THZ-100 thermostat and/or
remote sensor

• In an open living area where there is good air circulation

• On an inside wall

• Away from outside doors or windows

• At a height about 5 feet from the floor

Avoid installing the THZ-100 thermostat and/or remote sensor

• In direct sunlight

• Above radiators or air vents

• Near fans or portable heating units

• Near lamps or other incandescent lighting

• Near other heat generating electric appliances such as
televisions, audio video equipment, refrigerators, freezers,
ovens, cooktops, etc.

Other precautions when installing the THZ-100 thermostat and/or
remote sensor

• Make sure the cutout for the HVAC wiring is no larger than
needed to make proper connections to the thermostat

• If there is a large air gap in the cutout for the HVAC wiring,
insulate around the wire and close off the air gap

• Make sure the air vents in the THZ-100 thermostat and/or
remote sensor are clear of dirt, dust, or any construction
material.

Operation For Your THZ-100 Thermostat

Your THZ-100 thermostat has been programmed by the MRX Advanced
Network System Controller system with your custom HVAC schedule of
heat and cool set points for the selected time periods for each day of the
week. In addition, the thermostat has been programmed by the MRX
Advanced Network System Controller for the type of HVAC equipment,
conventional or heat pump, the number of auxiliary heat and/or cool
stages, any remote sensors, and any pass code lockout code if desired.

Thermostat Display Information

Your THZ-100 thermostat features a color backlit LCD display with all the
information you need for easy operation. The top left of the screen has the
fan mode information while the top right of the screen has the current
system mode such as Heat or Cool.

The center of the screen displays the current temperature with different
backgrounds dependent upon whether the thermostat is in Heating,
Cooling or Idle mode. The small letter F or C at the lower right of the current
temperature indicates the temperature scale.

Directly above the current temperature is the name of the program mode
that is currently running: Morning, Day, Evening, Night, Vacation, Override,
Hold, or Hold to <time>. When the system is OFF there is no text in this
area.

Directly below the current temperature is information on the current comfort
range and the set points. This area is also used for notifications such as
Check Wireless, Check Network, or Check Filter which alternates on screen
with the set point information.

THZ-100 THERMOSTAT

At the bottom of the screen is a smart-key label to identify the current
function of the push button located directly below.

Changing the Mode (Cool, Heat, Auto, Off)

To change the mode of your HVAC system equipment between Cooling,
Heating, Auto (system will automatically change between cooling and
heating) or OFF enter the Options menu then access the Climate Modes
sub menu as described below.

Changing the Heating Temperature (Temperature Override)

To change the current heating temperature, press the Up or Down arrow
key on the thermostat. The thermostat screen shows the current temperature
on the left side and the desired temperature on the right side of the display.

Press the Up and Down arrow keys to set your new desired heating
temperature to override the programmed value. To save the new desired
value, press the key below the Set Tempkey label in the smart-key labeled
Set Temp at the bottom right of the display. You can also save the new
desired temperature by simply allowing the display to time out while the
current and desired override temperatures are displayed.

If you decide to cancel the operation, press the key below the Cancel key
label in the smart-key label at the bottom left of the display.

This places the thermostat in the Override mode. While in this mode, the
thermostat holds your new temperature selection until the next regularly
scheduled time period in your pre-programmed HVAC schedule.

Changing the Cooling Temperature (Temperature Override)

To change the current cooling temperature, press the Up or Down arrow
key on the thermostat. The screen now shows the current temperature on
the left side and the desired temperature on the right side of the display.

Press the Up and Down arrow keys to set your new desired cooling
temperature to override the program value. To save the new desired value,
press the key below the Set Temp key label in the smart-key label at the
bottom right of the display. You can also save the new desired
temperature by simply allowing the display to time out while the current
and desired override temperatures are displayed.

If you decide to cancel the operation then press the key below the Cancel
key label in the smart-key label at the bottom left of the display.

This places the thermostat in the Override mode. In the Override mode,
the thermostat holds your new temperature selection until the next regularly
scheduled time period in your pre-programmed HVAC schedule.

When the override set point is satisfied the information containing the
desired override temperature with transition to information including the
desired temperature and the heat and cool set points based on the override
temperature.

Auxiliary Heat

Auxiliary heat consists of additional stages of conventional gas, or electric
heat, capacity included with most heat pump systems. The auxiliary heat
stages are automatically selected by the system when the outside temperature
is too cold for the heat pump to heat your home effectively. The staging of
the auxiliary heat is based on the information selected in the MRX
Advanced Network System Controller setup of your thermostat.

Page 11

THZ-100 THERMOSTAT

Emergency Heat

Emergency heat is conventional gas, or electric heat, capacity included
with most heat pump systems. Emergency heat is selected by the user
from the Options menu as described below when additional heat capacity
is desired. Emergency heat reduces the energy efficiency of the heat pump
system. When in emergency heat, the display indicates this state in the
upper right of the display.

Intelligent Comfort Recovery

When there are significant set point differences between programmed
set points of different program time periods your THZ-100 anticipates
the change in advance and begins to ramp the current set point to the
next programmed set point to give you a smooth comfort transition.
During this comfort recovery period the thermostat indicates Comfort
in place of Heat, Cool, or Idle in the upper right of the display window.
In addition, the display background changes to indicate whether the
system is heating or cooling during this transition.
